Fact Check

The primary source, the Korea Economic Daily (Hankyung) article dated July 17, 2026, explicitly states that mutual conversion between SK Hynix's domestic common shares and US ADRs becomes possible from July 29, 2026, and that issuance caps, separate brokerage applications, and foreign-exchange procedures constrain share-to-ADR conversion while keeping the ADR premium above 50%. This matches the claim precisely. Bloomingbit (citing Hankyung), Odaily, and BlockBeats independently repeat the same details, and independent outlets (Financial Times, Straits Times) confirm both the July 29 conversion opening and the elevated ~51% premium. All key claim elements are corroborated by multiple sources.

Summary

SK Hynix investors are expected to be able to convert between the company’s ADRs and Seoul-listed common shares after July 29, when newly issued shares tied to the ADR issuance are listed in South Korea. Market participants still expect the ADRs to trade at a premium because arbitrage remains constrained by issuance caps, brokerage procedures and foreign-exchange steps when converting common shares into newly issued ADRs. As of July 17, the premium had widened to more than 50%, though a later move on Hyperliquid showed the gap narrowing by about 4 percentage points after the Korean market closed as the U.S.-traded SKHY fell 10.5% to $148.5 while Korea-listed SKHX fell 8.9% to $1134, according to Hyperinsight.
